By the end of October, new-type storage connected to the Shandong grid had reached 15.2316 GW, an increase of 56.38% year on year and among the largest provincial totals in China. At this scale, the connected storage fleet is estimated to help the province use an additional 6.1 billion kWh of clean electricity each year.

State Grid Shandong Electric Power is working across three areas: grid-connection services, dispatch and operation, and market mechanisms. Its aim is to support higher-quality storage development, strengthen grid flexibility and advance the development of a new power system.

For grid connection, the company organises technical assistance at three stages: early project development, construction and preparation for connection. A two-stage process combines advance pre-acceptance checks with formal acceptance to identify equipment and construction risks affecting grid safety. It has reduced the number of storage grid-connection steps by 50% and shortened the time required for dispatch agreements by 30%. Since the start of 2025, it has supported connection of 60 new-type storage projects with a combined capacity of 7.738 GW.

For operations, State Grid Shandong continues to improve coordinated dispatch of its multi-gigawatt storage resources. During summer peak demand, rapid response and flexible regulation supported renewable integration and electricity supply. On August 3, it coordinated evening-peak discharge from 172 storage stations, reaching a maximum output of 11.98 GW and setting a new national record for coordinated new-type storage dispatch by a provincial grid.

The company is also supporting improvements to electricity-market trading rules and the participation of independent and generation-associated storage in spot and ancillary-service markets. It encourages existing renewable stations to add or expand storage, improving their ability to regulate output and support the grid, smooth wind and solar fluctuations and coordinate renewable generation with storage.
